Where this sits among everything scored
Real-World Exposure
pyradReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
packet.py in pyrad before 2.1 uses weak random numbers to generate RADIUS authenticators and hash passwords, which makes it easier for remote attackers to obtain sensitive information via a brute force attack.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pyrad, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update pyrad to 2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2013-0294 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
